Protects data itself rather than the systems around it — classifying what you hold, encrypting in transit and at rest and understanding what each actually defends against, managing keys and their rotation, handling secrets in applications and pipelines, minimizing and de-identifying, and deleting on purpose. Use this to design data protection for a system, assess an encryption claim, set up key or secret management, or work out what a stolen backup would actually expose.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Data protection and encryption Perimeter and identity controls protect access to data. These controls protect the data when those have already failed, which is the scenario worth designing for. ## Classify before you protect, because you cannot protect everything equally A short scale beats a detailed one — three or four levels that people can apply without a manual. What matters is that each level carries concrete handling rules: where it may be stored, who may access it, whether it may leave the environment, and how long it is kept. **Find it before you classify it.** Sensitive data is rarely only where the architecture says it is: it accumulates in exports, analytics environments, test databases seeded from production, support tickets, and log files. ## Know what each kind of encryption actually defends against This is where claims get made loosely and expectations diverge from reality. - **In transit** protects against interception on the network. Enforce it everywhere, including internal service-to-service traffic, and prefer a modern configuration over one accumulated over years. …

How to install
mdr add cbrock84/headcount/data-protection-and-encryption@sha256:b325e8081f4399a5The line at the top of this page pins the label git:20260916.e72e404, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
